Fix OAuth server for macOS bash 3.x (#24)
Three issues broke the OAuth callback server on macOS:

1. echo -e doesn't work in bash 3.x — \r\n appears as literal text
   in the HTTP response, browser gets malformed headers.
   Fix: pre-write response with printf to a file before the subshell.

2. local variables inside ( ... ) & subshell — undefined behavior in
   bash 3.x since subshells aren't function scope.
   Fix: use plain variables in subshells.

3. ((elapsed++)) when elapsed=0 evaluates to falsy — set -e kills
   the script on the first iteration of the timeout loop.
   Fix: use elapsed=$((elapsed + 1)) instead.

Also simplified nc_listen detection to only check for BusyBox
(the -p flag check could misfire on macOS nc).

Applied to all 10 lib/common.sh files.
